This article is about the original A5093, the southern half of the Barnet Bypass.
For the current A5093, a loop off the A595 serving Millom, see A5093
Falloden Way (today part of the A1) in Hampstead Garden Suburb
The number A5093 was originally allocated to the southern half of the Barnet bypass. Leaving the A1 near East Finchley it headed northwest along Falloden Way and Great North Way to join the A5088 Watford bypass at the Fiveways junction at Hendon. The two bypasses diverged a couple of miles further north but the Barnet bypass was then numbered A5092.
In 1935, both sections of the Barnet bypass became the A555, and around 1954 the A1 was rerouted this way.
